DETAILED DESCRIPTION
[0023] The specific implementation manner of a semi-automatic foundation pit filling and leveling device provided by the utility model is further described in conjunction with the accompanying drawings and embodiments.
[0024] like Figure 1-2 As shown, a semi-automatic foundation pit filling and leveling device comprises a bulldozer device 1, a driving device 2 and a roller 3. Preferably, the bulldozer device 1 comprises a front bulldozer plate 11, a screen 12 and a connecting plate 3, the connecting plate 3 of the bulldozer device 1 is connected to the front end of the driving device 2 through an electric telescopic rod 5; the roller 3 is arranged at the rear end of the driving device 2; both ends of the axle of the roller 3 are connected to the driving device 2 through a connecting rod 29; and a soil storage and transfer device 4 is slidably arranged directly below the driving device 2.
[0025] like Figure 3 As shown, the driving device 2 includes a chassis 21, and driving wheels 24 are arranged on both sides of the bottom of the chassis. The surface of the driving wheel 24 is provided with a track 23, wherein the driving wheel and the track belong to the prior art, and any driving wheel and track that can achieve movement or steering can be used, and no further details are given here. The chassis 21 is provided with a first motor 22, a second motor 26 and a roller 28; wherein the driving wheel 24 is controlled by the first motor 22; the output shaft sleeve of the second motor 26 is provided with a transmission gear 27, and the transmission gear 27 is meshed with the tooth pattern on the surface of the roller 28; the two ends of the roller 28 are respectively connected to the connecting rod 29; it is worth noting that the forward and reverse directions of the roller can be rotated by controlling the forward and reverse rotation of the second motor 26, thereby driving the connecting rods at both ends of the roller to flip, thereby realizing the lifting and lowering adjustment of the roller 3, and realizing the compaction requirements of foundation pits with different elevations, and the roller 3 can improve the compaction degree through its own transmission.
[0026] Preferably, a positioning rail 25 is provided at the front end of the roller 28 near the side of the shovel device 1, and two laser emitters 251 are slidably provided on the top of the positioning rail 25. By adjusting the position of the laser emitter 251, the running track of the device can be controlled so that it does not deviate, thereby ensuring the filling and leveling effect; Figure 4As shown, the bottom plate of the chassis 21 is symmetrically provided with two slide grooves 30, and a limit stopper 31 is also provided at the bottom of the chassis 21. The stopper 31 is arranged at one end of the slide groove 30 close to the shovel device 1, in order to limit its card-in position when the soil storage and transfer device 4 moves to the bottom of the driving device 2.
[0027] like Figure 5 As shown, the soil storage and transfer device 4 includes a storage box with an opening at the front end, and the storage box includes a rear shovel plate 41, a remote control wheel 44 and a slider 45; wherein the rear shovel plate 41 is arranged at the front end of the storage box bottom plate; the remote control wheel 44 is symmetrically arranged on the storage box bottom plate; the slider 45 is arranged at the top of the storage box, corresponding to the position of the slide 30, and it is worth noting that the size of the slider 45 is adapted to the size of the slide 30 to ensure the fit between the two; the top of the storage box bottom plate is also provided with a pressure sensor 42 and a remote control signal receiver 43. The soil storage and transfer device 4 controls the movement of the remote control wheel 44 through the remote control handle through the remote control signal receiver 43, so as to realize the movement of the soil storage and transfer device 4 from directly below the driving device 2 in or out, and the pressure sensor 42 is mainly used to detect the weight of the soil stored in the storage box of the soil storage and transfer device 4. When the soil reaches 95% of the actual load, the pressure sensor 42 sends a signal indication, and at this time, the staff can control the soil storage and transfer device 4 to move out and empty or replace the empty soil storage and transfer device 4 through the remote control handle.
[0028] Preferably, the standard load of the soil storage and transfer device 4 is selected according to the actual conditions of the foundation, and a storage box with a standard load of 100KG, 300KG or 500KG can be selected.
[0029] Also preferably, in order to ensure that the construction is not restricted by night or light conditions, lighting lamps 131 are provided on both sides of the connecting plate 13 .
[0030] Further preferably, in order to ensure the overall connection strength of the device, the connection plate 13 is made of steel.
[0031] It is worth noting that in order to ensure the filling effect, the screen 12 needs to fit the ground.
[0032] When in use, first turn on the second motor 26 to drive the transmission gear 27 to rotate, and then control the roller 28 to rotate, so that the connecting rod 29 connected to the two ends of the roller 28 is flipped up, and the roller 3 is lifted off the ground. When there is sufficient space between the roller 3 and the ground, the remote control handle is controlled to control the soil storage and transfer device 4 to slide along the slide groove 30 to the bottom of the drive device 2 until the front end stops against the limit block 31; then control the second motor 26 to rotate in the opposite direction, and lower the roller 3 to fit the ground.
[0033] Working principle: When the foundation pit needs to be filled, first put the accumulated soil into the push shovel device 1, turn on the device and move it forward. During the movement, the accumulated soil will fall into the area to be filled through the screen 12. If the area is large or deep, the movement speed of the device is reduced by controlling the rotation rate of the first motor 22 until it is filled and compacted by the roller 3. The excess accumulated soil is recovered by the rear soil storage and transfer device 4. When the foundation pit needs to be leveled, first empty the push shovel device 1. When the device moves to the raised area in the foundation pit, the soil in the raised part will be shoveled into the push shovel device 1 by the front shovel plate 11. As the device continues to move forward, the excess soil will leak out through the screen 2 and be recycled into the storage box of the soil storage and transfer device 4 through the rear shovel plate 41. When the soil in the storage box reaches 95% of the actual load, the pressure sensor device 42 sends a signal indication. At this time, the staff can control the soil storage and transfer device 4 to move out and empty or replace the empty soil storage and transfer device 4 through the remote control handle, and then continue to work.
[0034] The main operation route of the device is as follows: Figure 6 As shown, when working, first start from point A, aim the laser emitter 251 at point 1 and point 2 at point B in sequence, and then aim at point 3 and point 4 at point C when arriving at point B, and then aim at point 5 and point 6 at point D..., and work repeatedly in a clockwise direction in a U-shaped direction to ensure the overall flatness and design elevation of the foundation pit.
[0035] The utility model can effectively replace the method of using large-scale machinery to level the foundation pit and then use manual excavation for later fine work. By adjusting the height of the roller, the foundation pit can be leveled at one time after the design elevation of the foundation pit is determined. The leveling effect is good and is not limited by the light or weather conditions of the construction environment, which greatly improves the construction efficiency.
